The operatlng device Bcomprises a frame :or base section 5 in the formof a plate which is rigidly secured'to the door A by screws orequivalent fastenings 6 and which has a circular flange 7Q Infront ofthe base or back section 5 is a rotatable plate 8 which turns onecentral stud oripivot 9 screwed into a central boss 10 on'the backsection; 5,- and on this front section or plate 8 are fixed 5 pins 11which extend into the chamber 12 and engage in elongated openings 13 inthe :ofiset ends 14 of the locking bolts 1 and 2, "which latter enterthe casing of the locking device throughuopenings 15- in the circum-iferentialflange On the stud 9swings an operating handle 16 which hasavlost motion connection with the plate or disk 8, by reason of a pairof screws 17 and 18, which screwhinto the under side of the handle andare engaged respectively in slots 17 and 18. in the disk 8. The head ofthe screw 17 is countersunk in the disk 8 and :the slot 18? for thescrew 18 islocated in anextension 19 in one edge of of this extensionare spaced lugs 20 which are adapted to engage the bosses 21 on the base7 section to limit the swinging movement of the handle 16, asclearlyshown in Fig.6.,
